Moving a Unity Animator component to its parent


In VALA I’ve been animating a cut-scene, and made the silly mistake of putting my Animator component on the character instead of on a root object. This means that the Animator isn’t able to move anything except the character (because they are not in the same hierarchy).

In the image below, my Animator was on Scientist, instead of ScientistRoot, meaning that I couldn’t use it to animate ScientistTerminal when he touches it.

So here is a quick tip to move the Animator to the root GameObject – which Unity doesn’t support, but really should.

Some details on the eThekwini Municipality vulnerability

Here are some extra details on what happened yesterday.

Here is the MyBroadband article for context.

Timeline

At 12pm 7 September a colleague of mine received the email from eThekwini, and told me the password was in plain text.

Presumably they were staging emails because at at 4:31pm 7 September I received the same email. The password was in plain-text, and was my actual password, not a newly generated one.
This means they were either storing the passwords in plain-text, or encrypting them and storing that – both of which are obviously bad, because if they can decrypt it, chances are so can someone else.

FlappyHand: Unity3D game with an ESP8266 Arduino (Wemos) controller over WiFi

I thought it would be fun to make a little FlappyBird clone using an ultrasonic sensor as the controller.
So I threw this together yesterday:

What you’re seeing there is an ultrasonic sensor on the table reading how far my hand is away from it, then it sends that value over WiFi to the Unity3D game, which then maps that to the plane movements.

Unity3D Mesh Collider vs. Box Collider

Logic tells us that a box collider in Unity3D will be more performant than a mesh collider simply because it is less complex. But I had an impulse a couple days ago to test it out myself. This doesn’t really scratch the surface of every use-case.

I went to the AssetStore and picked out a fairly simple free armchair model. I then made two different prefabs, one with a convex mesh collider, and the other with a box collider.

Chair collidersThen I made a script to spawn a 40×40 grid of a type and let them fall onto two planes. That means a total of 1600 armchairs were doing discrete physics updates, which will kill even the best of the PC master-race.

 

On the left side we have the mesh collider, and on the right is the box collider. Click the gif to goto a full-size version which has a bar to manually scrub through.

As expected, the summary is that the mesh collider is incredibly slower (sometimes even 20x slower) than the box collider. And in this case the mesh collider is actually pretty simple. Something worth pointing out is that although the graphs sort of line up, their scale is totally different, so take a proper look at the number on it.

 

Now for bonus points, here is a pretty scene of a stupid amount of spheres attacking the streets of New York.

Nuget: Your project.json doesn’t list ‘win10-x86’ as a targeted runtime

Recently I was working on a small UWP app on my SurfaceBook and everything was fine. But when I pulled the code from GitHub down to my main machine I got the following error:

Your project.json doesn’t list ‘win10-x86’ as a targeted runtime. You should add ‘”win10-x86″: { }’ inside your “runtimes” section in your project.json, and then re-run NuGet restore. 

After a while I figured out that this error is totally misleading, and the real problem is that your Nuget package source has been disabled. I have a feeling this was related to installing Visual Studio 15 preview.

Anyway, to fix it: Click Tools > Options > NuGet Package Manager > Package Sources, and then re-enable (or re-add) the sources.NuGet Package Manager

Full Netflix vs ShowMax South Africa Catalogues

A couple of years ago I wrote a guide for getting Netflix in South Africa, which still gets thousands of hits a month. A lot has changed since then – notably, Netflix has finally launched in South Africa, and a bunch of local VOD services have launched (ShowMax, Vidi, and some other small ones).

But even though Netflix is now in SA, the content is really limited. This isn’t Netflix’ fault, but comes down to licensing and what makes commercial sense. For this reason, the guide linked at the top is still 100% valid, and will open up tons of extra content.

Since the Netflix SA launch there has been lots of media comparing Netflix with ShowMax (and others), however none of them really go into any detail, and the actual data they have seems pretty inaccurate.

So I crunched the numbers!

Simple network discovery to find Netduinos from Windows

With the advent of Internet-of-Things things, you’ll probably need a decent way to actually find all of the things on your network.

Fun fact: If you send a UDP packet to *.255 on your network, your router will then send that along to all the devices on your network. So if your local network is on 192.168.1.x, then send it to 192.168.1.255. Or if you want to send it to everything, then you can send to 255.255.255.255.

In my case, I’ve got this awesome little guy…

…setup with DHCP, so the IP occasionally changes. I’ve got a Windows 10 app that needs to connect to it, so we can use the way above to find the Netduino on the network.
